Features
1. Description
The AT49BV322A(T) is a 2.7-volt 32-megabit Flash memory organized as 2,097,152
words of 16 bits each or 4,194,304 bytes of 8 bits each. The x16 data appears on
I/O0 - I/O15; the x8 data appears on I/O0 - I/O7. The memory is divided into 71 sec-
tors for erase operations. The device is offered in a 48-lead TSOP and a 48-ball
CBGA package. The device has CE and OE control signals to avoid any bus conten-
tion. This device can be read or reprogrammed using a single power supply, making it
ideally suited for in-system programming.
The device powers on in the read mode. Command sequences are used to place the
device in other operation modes such as program and erase. The device has the
capability to protect the data in any sector (see
To increase the flexibility of the device, it contains an Erase Suspend and Program
Suspend feature. This feature will put the erase or program on hold for any amount of
time and let the user read data from or program data to any of the remaining sectors
within the memory. The end of a program or an erase cycle is detected by the
READY/BUSY pin, Data Polling or by the toggle bit.

The x16 data appears on I/O0 - I/O15; the x8 data appears on I/O0 - I/O7. The memory is divided into 71 sec- tors for erase operations.

... If the BYTE pin is set at logic “0”, the device is in byte configuration, and only data I/O pins I/O0 - I/O7 are active and controlled by CE and OE. The data I/O pins I/O8 - I/O14 are tri-stated, and the I/O15 pin is used as an input for the LSB (A-1) address function. AT49BV322A(T) 2 input is below 0.4V, the program and erase ...

... Read The AT49BV322A(T) is accessed like an EPROM. When CE and OE are low and WE is high, the data stored at the memory location determined by the address pins are asserted on the out- puts. The outputs are put in the high impedance state whenever high. This dual-line control gives designers flexibility in preventing bus contention ...

... Data Polling feature or the Toggle Bit feature may be used to indicate the end of a program cycle. If the erase/program status bit is a “1”, the device was not able to verify that the erase or program operation was performed successfully. 3308J–FLASH–4/05 AT49BV322A(T) .

... Data Polling The AT49BV322A(T) features Data Polling to indicate the end of a program cycle. If the status configuration register is set to a “00”, during a program cycle an attempted read of the last byte/word loaded will result in the complement of the loaded data on I/O7. Once the program cycle has been completed, true data is valid on all outputs and the next cycle may begin. During a chip or sector erase operation, an attempt to read the device will give a “ ...

... VPP Status Bit The AT49BV322A(T) provides a status bit on I/O3, which provides information regarding the voltage level of the VPP pin. During a program or erase operation, if the voltage on the VPP pin is not high enough to perform the desired operation successfully, the I/O3 status bit will be a “1”. ...

... Protection Register The AT49BV322A(T) contains a 128-bit register that can be used for security purposes in sys- tem design. The protection register is divided into two 64-bit blocks. The two blocks are designated as block A and block B. The data in block A is non-changeable and is programmed at the factory with a unique number ...

... Hardware Data Protection The Hardware Data Protection feature protects against inadvertent programs to the AT49BV322A(T) in the following ways: (a) V function is inhibited. (b) V device will automatically time out 10 ms (typical) before programming. (c) Program inhibit: hold- ing any one of OE low, CE high or WE high inhibits program cycles. (d) Program inhibit: V less than V ations are inhibited for 100 ns ...
